3.4.2 Hearth Extension Requirements
The LE LAVAL fireplace may be installed directly on a combustible floor; however, the
combustible floor in front of the fireplace must be covered with a half inch (1/2 in.) of non-
combustible support material (cement board, cement block or other) before applying the finish
material (tile, marble, stone, etc.) (see figure 7 & 7.1).
WARNING: It is important not to cover the air ventilation opening below the facade trim.
(free space fig. 7.1)
Elevated fireplace (figure 7.2)
Elevated fireplace installations require a special „Z‟
metal safety strip (field provided), in place of the
safety metal strip shown on figure 7.1. The safety
strip should extend the full width of the fireplace.
When more than one strip are used, they must
overlap by a minimum of 1 inch.
Hearth extension of an elevated fireplace must
respect the same minimal dimensions as a fireplace
installed directly on the floor (figure 7).
Figure 7
Warning : The hearth extension is to be installed only as illustrated.
Note : The crack between the fireplace and the hearth extension
must be sealed with a non-combustible material such as a
non-combustible sealing strip or sand cement grout in the
area specified above.
